ARTERIAL SYSTEM.

This is a system by which blood is carried by the heart to all parts of the body.

ARTERIES:
All arteries carry oxygenated blood to various parts of the body, except the pulmonary artery.


TRUNCHUS ARTERY:
The trunchus artery is divided into two branches, each of them are divided into 3 arches. They are:
1) Pulmocutaneous Arch.
2) Carotid Arch.
3) Systemic Arch.

PULMOCUTANEOUS ARCH:
It is further divided into the following arteries.
1) Pulmonary artery.
2) Cutaneous artery.

Pulmonary Artery:
it carries De-oxygenated blood to the lungs.
Cutaneous Artery:
It supplies blood to the skin.

CAROTID ARCH:
It is divided into two arteries.
1) Lingual artery.
2) Carotid artery.

Lingual artery:
It supplies blood to the tongue.
Carotid artery:
It supplies blood to the following arteries.
1) Orrbital Artery.
It supplies blood to the orbit and the roof of the buccal cavity.
2) Cerebral artery:
It supplies blood to the brain.

SYSTEMIC ARCH:
The two systemic arches unite and form a main vessel called dorsal aorta. Each systemic arch before uniting with its fellow opposite side has the following three branches.

1)Oesophagus artery:
It supplies blood to the oesophagus.
2) Subclavian artery:
It gives small branches to the shoulders and then passes into the fore limbs.
3)Occipital Vertebral artery;
its is divided into two arteries.
Occipital artery:
It goes to the side of the head.
Vertebral artery:
It supplies blood to the muscles of the back and spinal cord.


DORSAL AORTA:
It is the main artery. it passes between the kidneys and finally reaches the hind limbs. From it the following arteries arise;

Coeliaco Mesentric artery:
It arises from the point of the union of the two systemic arches. It is divided into anterior mesentric artery, posterior mesentric artery and celiac artery.

Anterior Mesentric artery:
Its is divided into the following arteries;
Intestinal artery:
it supplies blood to the intestine.
Spleenic artery:
It supplies blood to the spleen.
Pancreatic artery:
It supplies blood to the pancreas.
Celioc artery:
It supplies blood to the stomach.

Posterior Mesentric artery:
It supplies blood to the rectum.

Hepatic artery:
It supplies blood to the liver.

Spermatic and Ovarian artery:
They arise from the most interior renal artery. In male they are called spermatic artery and in female they are called ovarian artery.

Renal artery:
They are four and they supply blood to the kidneys.

Illiac artery:
It supplies blood to the hind limbs.
